This invention relates to improvements in ice shaving devices. 7

The principal object of this invention is to provide a uniquedevice for shaving ice to realize an edible ice confection and for the that apositive wedging' action of the ice will be realized whereby ice will be retained in a fixed position and can be readily contacted by the internally disposed blades of the rotating drum to thus assure arapid and positive cutting of the ice to the desired degree of fineness.

A further object is to produce a device which iscomparatively small and therefore portable and one which may be placed on a counter with other drink mixing machines.

A still further object is to produce a device which is neat in appearance, durable, economical to manufacture and positive'in operation. v

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughoutthe same,

Figure 1 isa vertical cross, section on an enlarged scale on the line 11 of Figure 4, 1 Figure 2 is a side elevation of the device,

Figure 3 is a transverse vertical section on an enlarged scale on the line 33 of Figure 2, Figure 4 is a front elevation of. the device, 1 and V 1 Figure 5 is a fragmentarydetail view showing the shaving knives asthey appear at-' tached to the rotating drum.

In the mixing of drinks at soda fountains it has been customary to have on hand aquan tity of broken ice, which is kept in a receptacle and a small amount scooped out into the drink being dispensed. The result is that the smaller particles of icerapidly meltleav- A ing only larger pieces which when placed in glasses are still floating in the drink when the same is served tothe customer. Manyserious accidentshave occurred through the customer choking on these pieces of ice' and at best the drink is 'not as pleasant if-it is necessary to hold back chunksof ice in the glass' A v 1 Applicant has therefore produced amachine wherein the ice is shaved into small chips at the time the drink is served thereby obviatingthe objections above noted. Atthe same time this device has a capacity great 7 enough to enable the user to dispense iced fiavorsa's are now common at many beachresorts, the same consisting merely in a quantity of shaved ice upon which a flavor-, ing has been poured,"th'e customereating this a flavored 's'nowball p V In theaccompanyingdrawings wherein for the purpose of illustration is showna preferred embodiment of my invention, the numeral 5 designates a base whichis adapted to rest upon a counter orother suitable-support. Mounted upon the base is a -motor'6having a housing 7which housing is providedwith a recess portion 8 into which the glass orother receptacle, to be filled with the shaved ice, is placed, This glass is designated by the-numera l 9. Supported above the glass 9 by the housing 7 is a non-rotating baflle 12 having arms 13 and 14,.while'surrounding this b'aflle" is a drum 16 journaled as at 17 upon the shaft 11 and upon the annular bearing 18. 'Th-is drum is provided Withslots 19 and has secured to its interior surface adjacent its slots, shaving blades 21. 5 j Y I -The numeral 22 designates a hopper that serves to feed ice'to the interior of the drum' through an opening 23 in the side of the housing- A discharge spout 24 is so arranged that the shaved ice will be dispensed into the glass9; i i Y As designated'to advantage in Figure 1, the

flavored icein a manner similar to that of numeral 26 designates a switch-arm so pivoted, that when the glass 9 engages the-same, engagement will'be-made with the contact 27 completing the electrical circuit to the motor 6. Any convenient means may be employed forconnecting the gear 28 of the motor with a gear 29 upon the drum 16. This connecting means is shown on dotted lines of Figures 1 and 3.

The result of this construction is that when a glass is placed in the position shown in the drawings, the same will cause the switch arm to complete the electrical circuit to the motor which will in turn rotate the drum 16 and the attached knives 21. Ice placed in the hopper 22 will pass into the drum and will be pushed by the bafiie arm 14 against the surface of the drum. The battle arm 13 prevents the ice from falling upon the wrong side of the bafile arm 14.

It will thus be seen that it is merely necessary to place ice in the hopper and to place the glass in the device in order to receive within the glass any given quantity of finely shaved ice particles;

From, the foregoing description considered in conneotionwith the accompanying draw ing it will be obvious that I have devised a unique principle of shaving ice while the same is disposed within rotating drum, andthe feature of employing a baffle that serves to wedge the ice whereby the same will be pushed againstthe internally disposed rotating blades thus assuring apositive shaving of the ice to the desired degree of fineness.

While I have disclosed a horizontally disposed rotating drum and a stationary bafiie, it is obvious that a vertical drum and a rotating bafile could likewise be utilized to accomplish the objects above set forth.

It is to be understood that the form of my invention herewith shown and described is tobe taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention, or the scope of the subjoined claim.

Having thus described my invention, I claim V In a device of the character described, a-

base, a housing positioned on said base, a'

drum 'rotatably supported in said housing, a motor supported on said base, said drum being adapted to be rotated by said motor, a recess formed in said housing, a hopper secured to said housing and adapted to feed ice to the interior of said drum, said drum being provided with slots, blades carried by said drum I and positioned adjacent said slots, a discharge spout adapted to receive shaved ice from sald drum and deposited 111 a glass p0 sitioned within said recess, and a baffle immovably held within said drum, said bafiie having arms extending into close proximity with the knives carried by said drum.

In testimony whereof I affix my signature.
